Prompt 4.7 distills a 31-page guide into practical prompts for Claude 4.7 (Opus 4.7). It presents concrete prompting changes—defining scope, controlling length and format, and using positive, actionable language—to yield more predictable outputs. The piece also covers how to instruct Claude to use tools and tailor tone and style for creative tasks.
Key Takeaways
- Explicit scope and named outputs: specify what Claude should produce, the order, and boundaries.
- Length, format, and structure: define exact output length, bullet counts, word limits, and starting verbs.
- Positive, action-oriented prompts: use direct instructions and concrete language; avoid negative framing.
- Tool usage and tone controls: Claude 4.7 uses fewer tools by default; prompt for more tool use if needed and set the tone (direct vs. warm) via input.
